A reporter for a New York newspaper, Wally Cook (Janet Leigh), hears of Homer's plight and convinces her editor, Oliver Stone (Fred Clark), to give Flagg an all-expenses paid trip to fulfil his life-long fantasy of seeing New York City. Meanwhile, Harris realizes that he made an error and Flagg is only suffering from a sinus condition. Harris agrees to keep this new diagnosis a secret after Flagg begs him... and after he meets Cook. To cover the secret, Harris announces that only he can provide medical treatment to Flagg and he must accompany him on the trip.
New York City embraces Flagg and he becomes a celebrity, with everyone following his every move in the paper. He even makes plans to marry Cook, despite the fact that she has fallen for Harris. Meanwhile, Stone is anxious for Flagg to die, as every day it is costing the newspaper money to support Flagg's extravagant lifestyle, which includes ordering 3,000 shrimp cocktails for his hotel suite. He hires three specialists to examine Flagg, who give him a clean bill of health. To escape the situation that they have gotten themselves into, Flagg fakes his suicide and the newspaper gets the exclusive story. Cook marries Harris, and Harris and Flagg become street sweepers in New York City.
